<h2>Create Assignment </h2>
<p style="margin-bottom: 0cm;">This tab opens a widget, where
registered users can create an assignment and save it in the
database, edit an existing assignment, or export it as an XML file to the local 
file system, or even import an assignment from an XML file.<BR>An assignment consists
 of a relational-database schema in
universal-relation form (URF), i.e., all the attributes in a single relation and a set of
FDs on the attributes.</p>

<p style="margin-bottom: 0cm;"><b>Load in SA Tab</b></p>
<p style="margin-bottom: 0cm;">Loads an assignment in the <i>Solve Assignment</i> tab without
saving it in the database first. <u>You do not need to log in to use this function.</u> This 
functionality could be useful for testing purposes.</p>

updated, rather then saved as a new entity in the database.</p>

<p style="margin-bottom: 0cm;"><b>Edit</b></p>
<p style="margin-bottom: 0cm;">Loads an assignment from the DB. Next
time you hit the Save button, the assignment will be updated in the

<p style="margin-bottom: 0cm;"><b>Export</b></p>
<p style="margin-bottom: 0cm;">Exports the current working assignment to the 
local file system, thus an assignemtn does not need to be stored in the DB in

<p style="margin-bottom: 0cm;">Imports an assignment from an XML file from the 
local file system. The imported assignment is set as a working assignment, thus
